A little over a month ago, Facebook announced they were buying the maker of the Oculus Rift headset for upwards of $2 billion. Now suddenly another company claims it's their technology that make the virtual reality device worth buying. ZeniMax Media has sent multiple letters to Oculus and Facebook, claiming employee John Carmack "improperly took ZeniMax's intellectual property with him to Oculus." Carmack was a former id Software (owned by ZeniMax) employee. ZeniMax claims the information Carmack took is what helped Oculus become so successful.
However, ZeniMax did not start sending letters until the knowledge that Facebook was acquiring Oculus went public, which is raising eyebrows. An Oculus representative told The Wall Street Journal, "It's unfortunate, but when there's this type of transaction, people come out of the woodwork with ridiculous and absurd claims. We intend to vigorously defend Oculus and its investors to the fullest extent."
When Carmack went from ZeniMax to Oculus last summer, five other ZeniMax employees followed. ZeniMax wrote this in a letter to the Oculus lawyers and Facebook's general counsel: "It was only through the concerted efforts of Mr. Carmack, using technology developed over many years at, and owned by, ZeniMax, that Mr. Luckey [founder of Oculus] was able to transform his garage-based pipe dream into a working reality."
